180=-2x+30
x=-75
i think this is what we’re supposed to do
Alright
so equation is
![A(t)=Pe^{rt}](https://tex.z-dn.net/?f=A%28t%29%3DPe%5E%7Brt%7D)
P=initial amount
and t=time
r=rate
given
initial amount is 50
rate is 10%, but decreasing by 10% so -0.1
and time=6
![A(6)=50e^{-0.1*6}](https://tex.z-dn.net/?f=A%286%29%3D50e%5E%7B-0.1%2A6%7D)
![A(6)=50e^{-0.6}](https://tex.z-dn.net/?f=A%286%29%3D50e%5E%7B-0.6%7D)
A(6)=27.4406
